Billy Currington may be on top of the world with his thriving career and good looks. But the singer admits there is one thing lacking in his life -- a significant other!

"I don't have a girlfriend," he recently told Seattle's KKWF radio. "I really want one, though. I really do want one."

Told that newly single Jessica Simpson mentioned that she thought Billy was cute, he recounted a jab the singer directed at him a few months ago, when she was still dating Dallas Cowboy Tony Romo. "We did a show in San Antonio together not too long ago," he remembers. "I sang my song and then it was her time, and she looked at me and she's like, 'So you think you're some cowboy ... with your cargo pants and your flip-flops? Well I got a real cowboy.' And she got booed!"

Still, Billy did offer a temporary fix to help Jessica get over her broken heart. "I'm up for a one-night stand anytime!" he said, quickly adding, "I only want it for one night though. No more than one night. That's high-maintenance there ... I'm in if you can hook it up!"

Billy's current single, 'People Are Crazy,' is at No. 1 on the country charts.
